After railroads made the region accessible in the late 19th century, coastal Maine became a fashionable destination for wealthy summer people. Many of the newcomers bought and restored the fine old houses built during the prosperous years following the American Revolution. In 1898, Mrs. Emily Tyson and her stepdaughter, Elise, purchased the c. 1785 Hamilton House, built on a site overlooking the Salmon Falls River. The Tysons flung themselves into a lifelong project to restore the house to its former glory. Influenced by literary imagery, including the writings of their neighbor and friend, Sarah Orne Jewett, they decorated with a mixture of elegant antiques, painted murals, and simple country furnishings to create their own romantic interpretation of America's colonial past.

The house offers tours and educational and recreational programs.

Historic Cherry Hill is a 1787 residence, occupied by the Van Rensselaer family until 1963. The site presents the changing culture, decorative arts, economic climate, and social classes of the 176 years in which the home was in use. The structure exists in its 1963 state in order to render social and architectural evolution visible to visitors. The Van Rensselaers were originally considered Hudson River manor lords, members of a group of wealthy local Dutch settlers. However, as early as the 1820s, the family began to face economic pressure which would increase with the formation of the millionaire class and the large numbers of immigrants entering the U.S. Collections include more than 20,000 artifacts—from the most mundane household items to rare examples of decorative arts styles—and 30,000 archival documents.

Cherry Hill offers period rooms; tours; interactive educational programs for students; and educational outreach programs for students. Reservations are required for groups of 10 or more. Listening assistance devices are available. The website offers two teaching units for purchase. Both won awards from the American Association for State and Local History.

Tours and on site educational programs are currently unavailable, as the site undergoes restoration. Outreach programming is still available.

The Justin Smith Morrill Homestead preserves the Greek Revival cottage of John Smith Morrill (1810-1898). During his life, Morrill worked as a blacksmith, merchant's clerk, Representative, and U.S. Senator. Unable to finish school himself, Morrill became the chief sponsor of the 1862 Land Grant Act. The act provided for a college in each state which would teach skills not previously available in the higher education system—practical science, agriculture, and engineering. These colleges also offered more traditional studies. Morrill's hobbies included architecture and landscape design.

The homestead offers period rooms, tours, gardens, and access to Morrill's library. Please call ahead to verify admission hours. Appointments are required for library access. The website offers suggested reading and a video virtual garden tour.

Adjacent to the rolling hills and open meadows of Osbornedale State Park, the recently renovated Osborne Homestead Museum encompasses the house and grounds of the former Frances Osborne Kellogg Estate.

Its restored interior now displays the original contents of the estate, which constitutes a significant collection of antiques and fine arts.

From Crazy Horse to the cavalry to the K-9 Corps, Fort Robinson played host to them all. Visitors to the site can experience the long and varied history of this outpost on the Plains.

Museum exhibits trace the history from the post's role guarding the Red Cloud Agency (1874–77) through the housing of World War II German POWs (1943–46). Among the many fascinating objects in the museum's exhibits are the only known dog kennel from the K-9 Corps of World War II; marksmanship medals earned by Caleb Benson, a Buffalo Soldier at Fort Robinson between 1902 and 1909; and 19th-century Sioux objects related to the Red Cloud Agency.
